Hi Richard, it is definitely a scaling artifact. An I believe that newer versions of rrdtool may use different fonts than older ones.
As I wrote, removing the explicit geometry settings brings back the good crendering, but now the images are of different size and this looks ugly too :-( So, now I can decide what kind of ugliness to tolerate ...
